我一直在尝试在新的React Native应用程序中设置react-navigation
。当我运行代码/屏幕时,Jest在按照v4 docs添加库后导致我出现问题。
我安装了react-navigation
,react-native-reanimated
,react-native-gesture-handler
和react-native-screens@^1.0.0-alpha.23
。然后,我进入ios
文件夹并运行pod install
。因为我使用的是React Native v0.61,所以它们应该已经自动链接了。
当我运行默认的Jest测试时,出现类似以下错误:
✓ renders correctly (106ms)
console.warn node_modules/react-native/Libraries/Animated/src/NativeAnimatedHelper.js:270
Animated: `useNativeDriver` is not supported because the native animated module is missing. Falling back to JS-based animation. To resolve this, add `RCTAnimation` module to this app, or remove `useNativeDriver`. More info: https://github.com/facebook/react-native/issues/11094#issuecomment-263240420
我搜索了此错误,建议的大多数答案是将其放在测试文件中:
jest.mock('NativeAnimatedHelper');
但是,当我尝试这样做时,Jest抱怨这样的错误:
FAIL __tests__/App-test.tsx
● Test suite failed to run
Cannot find module 'NativeAnimatedHelper' from 'App-test.tsx'
6 | import renderer from 'react-test-renderer'
7 |
> 8 | jest.mock('NativeAnimatedHelper')
| ^

10 | it('renders correctly', () => {
11 | renderer.create(<App />)
at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:259:17)
at Object.<anonymous> (__tests__/App-test.tsx:8:1)
我一段时间以来一直在尝试各种事情,任何帮助/建议将不胜感激!
